Specification of Letters Patent.

Application filed October 16, 1907. Serial. No. 397,643.

To all whom it muy concern:

Be it known that I, WILLIAM G. MARR, of New Britain, in the county of Hartford and State of Connecticut, have invented certain new. and,usefu1 Improvements in Spring- Wheels, of which the following is e speciictition.

My invention relates to improvements in spring wheels and the object of my invention is to produce a wheel with n flexible rim supported by springs.

Figure l is n sectional view of the rim at line 1 1 on Fig. 2. Fig 2 is a .longitudinal cross sectional View of n part of the wheel showing the rim sections and plunger-s 21tteched. Fig. 3 is n view of n port of the rim showing means for attaching the plunger-s and sections. Fig. 4 is n View of the slot 14. Fig. 5 is another view of the slot 14 showing the seme cutaway at l2, permitting the sections to be disconnected without removing the pivot 15.

The tire is shown et l; and 3 represent the rim sections, 4 the plungers, 5 the point of attachment of the plungers and the rim sections, by means ol' the opening 1() and the bolt ll; 6 represents the coiled springs; 7 a stop which is attaehed to ezieh ofthe rim seetions; S represents the l'ellv ofthe wheel and E) a bnud of metnl supportingl the springs.

li) represents a detachable support l'or the plunger, i7 n detaelndile eup having :l de.- tacliablo end 1S, and It a stop which muy be dispensed with il` desired, 'ns the support nfliorded by the nttaehment ol' thi` rim sections together will holdthe pnrts in position, '.lhe. rim sections 2 and I3 are attached to the plunger 4 b v means ol' pivots aud are hinged upon the plunger, the ends oll the rim sections are attnehcd together by means ol' the elongated hole let and a pivot 15 or the equivalent.

'l`he stop 7 is so arranged as to prevent the action oi' the springs i'roni l'oreing the rim sections out ol position. is elemlv illustrated in Fig. 2,' this stop comprises n pnir of looped. members hnving limited movement townrd and from eneh other al'ter the manner of the links ol a chain. lt is appar` ent therefore, thnt when these links have reached their limit of movement awav from each other, they limit further movement of the outer rim away from the inner rim. The construction of this stop, as shown in the drawing minv be changed and it is apparent that :i chain or the equivalent may be' substituted. I

Hoving thusdescribed my invention what I cleiin as new and desire to secure by Letters Potent is:

l. A vehicle wheel comprising en inner rim and. en outer rim composed of n plurality ofy sections pivotnlly connected to each other in suoli manner as to 1 ermit endwise movement of said sections with relation to each other, plungers pivotnlly connected to some of sind sections, n guide for said plunger carried by the inner rim, n plurality of cxible members connecting the inner and outer rims and limiting the outward nievement of the. outer rim with relation to the inner rim, und resilient members bearing between the inner und outer rims.

2. A vehicle wheel comprising nn inner rim and an outer rim con'iposed of n pluralit v of sections pivotalli' connected to euch other in such mnnner as to permit endwise movement of said sections with relation to each other, plungers pivotally connected to some ol' said sections, a guide for' seid plunger carried b v the inner rim, a plurality oli tiexible' members connecting the inner and outer rims und limiting the outward movement ol' the outer rim with relation to the inni-r rim, and resilient members bearing between the inner and outer rims, some oi' snid resilient members surrounding the plunger-s and other ol' sind resilient members surroumlingthe llexible members.

ln testimony whereoll l have allixed m signnture, in presenceI ottwo witnesses.
